During the patch downtime, existing players with the Combat Drone Operation skill trained will receive both new skills trained to the same level that their Combat Drone Operation skill was trained to.(Source)

So basically training this to maximum before the update (assuming you haven't already) would be as if you are training two skills at once! And more importantly, would prevent you from needing to train a skill with a longer training time after the patch, so you save EVEN MORE training time.
